dunno if the STS and dual exhaust is the perfect setup, but i can say i run a 170-172 60 since i changed to the bogarts and run NA times of 12.1x being my best at 110 mph and that was on a humid night. i run a dual exhaust No X pipe with 2 borla mufflers.your top end is bad *** from the trap speeds. have you always ran magnaflows? and which ones are they?

if its not that much trouble i would try the Y pipe vs. the dual exhaust

 

He has a maggie, not a sts.

 

the only diff was the cam swap and going from y pipe to x pipe

a lil spinning occurs , what concerns me more is the no nos times

 

yup its a maggie and im thinking of trying the y pipe swap to see if theres a diff

 

What rear gears?
This is a 2wd rcsb correct.

 

What was the temp difference? Though with the nitrous it shouldn't matter so much about heat.

 

Looks like you had a better driver last time LOL. Go back to "Y" pipe and single 3" exhaust and just play with your suspension. Truck should easily dip into the 11's without the juice. When was it sprayed this time? If my memory serves me right, I sprayed her right around the 60' mark, right where it started hooking.

 

this was sprayed just right after the line , and bout the temps they weren't that much of a diff

 

yes and 3.73s
